IMPROVED FIXTURE FOR RATCHET-WHEELS FOR LAMPS.

Specification forming part of Letters Patent No. 56,126, dated July 3, 1866.

To all whom it may concern:

Be it known that we, HoWEL TOPPING, of Marion, Wayne county, and MERRITT GALLY, of Auburn, Cayuga county, both in the State of New York, have invented a new and Improved Fixture for Lamps; and We do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in the use of slots in the sides of lamp-tops, for the passage of the shaft of the ratchetwheels which move the wick, together with a spring for regulating the pressure of the wheels against the wick, preventing the clogging of the tube heretofore experienced.

In order that those skilled in the art may manufacture and use our invention, We de scribe it as follows Figure 1 represents the fixture attached to Fig. 2 represents slots are made sufficiently long to allow the ratchet-wheels to be entirely withdrawn from the tube which holds the wick, and by so doing the wick may be easily placed in the tube, there being no obstruction.

O 0 represent a spring pressing against the shaft X X, and forcing the ratchet-Wheels against the wick when allowed to act; also, permitting the passage of wicks of different thickness, knots, or other obstructions caused by unevenness in the structure of the wick.

What we claim as our invention, and desire to secure by Letters Patent, is

The application of a spring to the shaft of the ratchet-wheels of a lamp-top, pressing the wheels against the wick, in combination with slots in the sides of the lamp-top, allowing the movement of said shaft for different degrees of compressure, substantially as herein set forth.

HOWEL TOPPING. MERRITT GALLY.
